Blinker Grounding Issue

Howdy All,

Here's my issue. Left turn signal stops blinking when brakes are applied about 75% of the time.

Here is what I have to do:

Turn on blinker (left)
Apply brakes
If blinker stops, I have to cycle the signal off then back on

A few years back, I replaced the MFS thinking that was the issue. It wasn't so I've just dealt with the issue. Now my Jeep is my daily driver and it's irritating me. I've searched the forum and came up with "check the ground for the lights".

Exactly where is this grounding connection that I need to check? Electrical is not one of my stellar areas of expertise.

I don't know if this applies to you, but I had a wierd grounding in my lights and I ended up finding it was the rusty screws that hold the taillight on. I replace the screw with some stainless steel ones and my issue went away. Might look into that.

The taillights 'ground' through the mounting screws.
I replaced the screws with some decent stainless nuts and bolts. You can tighten the nuts and bolts by pulling down the rear part of the plastic inner fender liner and reaching up into the cavity behind the taillights.
Not sure if yours is a grounding issue - grounding issues usually manifest with random or 'weak' flashing. Got to be worth a try though.
